Unfortunately, the manufacturer can not as accurate with the packaging of its screws and so we had to really perfect service from Amazon endeavor, because in the first delivery lacked all screws. In the second delivery of the screws bag of cardboard was also torn up, for it tight and we were able to gather all the screws from the carton. The manufacturer should work better. Otherwise, it is to build a little something to bicycle together and bring to. The wheels are held steady.
